Edit 2: I looked on the Wabi website and indeed the dust cover design has changed since I bought my new generation Wabi wheels that have the bolt-on design and are fixed-fixed. The dust covers are smaller on mine and clear the freewheel body where it tapers down past the threads. You may be able to fix this by placing a thin shim between the hub flange and the freewheel.
